Deployment Adjustments for Recovery & Hot-Swapping
Recovery only for all Cornell Rockhopper sites and UMCES sites T-2C, T-3C
Addition of VR2ARs in place of VR2Ws and Sonardyne acoustic releases for redeployed UMCES sites
- UMCES sites to be redeployed: T-1C, V5, A-5C, V4
Removal of co-deployed C-POD and LS-1X at sites T-1C and A-5C; VR2Ws replaced by VR2ARs
- Addition of Soundtrap at T-1C
Addition of an F-POD at site V5 and an LS-1X at site V4
Mooring configurations:
LS-1X and F-POD placement above VR2ARs (necessary for acoustic release mechanism)
F-POD and Soundtrap placement above VR2AR (modeling similar design used by WHOI shown below)
Estimated max. time needed at stations:
Rockhoppers - 15 mins
- Retrieval only
UMCES multi-device moorings - 15 to 45 mins
T-2C, T-3C – 15 mins
- F-POD + VR2W + Sonardyne AR recover
D1, D2 – 15 mins
- F-POD + Sonardyne AR recover
V4, V5 – 15 mins
VR2AR recover
VR2AR + LS-1X or F-POD redeploy
T-1C, A-5C – 45 mins
F-POD + C-POD + LS-1X + VR2W + Sonardyne AR recover
F-POD + Soundtrap + VR2AR redeploy
Day 1 - Tuesday, 23 April 2024
Goals: Recover 5 Rockhoppers, 2 solo F-PODs, 1 VR2AR, and 2 F-POD/VR2W moorings. Redeploy 1 F-POD/VR2AR and 1 LS-1X/VR2AR mooring.
